     * A viewContext is a simple string value which usually is set by a controller to define the context of a resulting view.
     * If a viewContext is set, it will be sent to the client in case of pjax and full page loads. The HumHub Client API
     * will then use the viewContext in all ajax (non pjax) requests as HTTP request header `HUMHUB-VIEW-CONTEXT`
     * until the next pjax or full page load.
     *
     * The viewContext is usually used to influence the view, e.g. a viewContext 'modal' indicates that the resulting view
     * will be contained in a modal, a 'dashboard' context will indicate that the ajax request was sent from the dashboard.
     *
     * A controller usually sets the viewContext within the init function e.g.:
     *
     * ```php
     * public function init()
     * {
     *   parent::init();
     *   $this->view->setViewContext('dashboard');
     * }
     * ```
     *
     * Note: This variable won't contain the value of the request header but is only used to set the client viewContext.
     * Use `Yii::$app->request->getViewContext()` to determine the active viewContext of a request.
